Secret 2 way Pattern Part Performance Boost.

The secret is to not use 2nd direction for part patterning. Use 2 pattern features instead for a lot of objects. This was a 15x15 pattern. I was playing around with tile floor pattern for @jeff_mcaffer and noticed a huge performance hit when clicking on 2nd direction in part pattern function. It might be tied just to the add option of the pattern feature trying to join all the geometry. I have to try a few other things to explore and expand if necessary.

This is because for 2nd direction, there are 15*15-1=224 Boolean adds, and for the 2 patterns there are 14+14=28 Boolean adds.
That makes sense. Maybe a case could be made for a IR to do only 28 adds in either situation.
I encourage everyone to read this:

That is good stuff. Thanks Neil.
I guess then for patterns such as in my example the best performance would simply be a pattern of 2 each time where possible.
Managed to do a 32x32 = 1024 pattern under 19 sec.
